Sol 1875-1876: Sitting on the Boundary

What makes this day a bit different than other days is that Curiosity is sitting right on the boundary between two geologic units observed from orbit.

What can LibGuides do for you?

“LibGuides are an easy to use content management and information sharing system designed specifically for libraries… I personally create guides most often when working with instructors who have asked me to meet with their classes for an information literacy session.”

Guest Post: A Virtual Rendez-Vous for Geoscience Research Around the North Atlantic

The following is a guest post authored by J.P. Walsh. The information and opinions are of Walsh and not my own.   While scientists in Europe enjoy their afternoon tea or café, North American researchers are beginning their day with a favorite beverage, maybe a Starbucks or Tim Horton’s coffee. We are thousands of kilometers apart, yet many of us are working on similar or related science. To be successful …

Not the water cycle or carbon cycle… but the Information Cycle

When students start an assignment, what’s missing from their approach is the idea of where their topic falls in the information cycle, and therefore, the first step in finding appropriate sources for their topic.

Lasers, Lunar Landings, and LRO

The young man was very interested in my work. I described how the tunable laser worked, how we were able to measure carbon dioxide and why it mattered. He was genuinely interested lasers and asked about other uses. I explained that laser can be used for cutting steel, measuring how fast cars are traveling, and as guide stars for observatories. I mentioned that scientists are able to accurately measure the distance to the moon by bouncing the lasers off or reflector arrays placed there by the Apollo astronauts. As I talked about the astronauts on the moon, I watched this guy’s face change. He thought for a minute and asked something like: You think we landed on the moon?

Cell Phone Spectrometer

Working with light and spectrometers is a part of my job. I worked with lab-built spectrometers and tunable lasers as a grad student at Montana State. At Los Alamos I worked with a mock-up of the ChemCam spectrometers and laser system. I still work with spectrometers at Apogee Instruments. I am also a smart-phone nerd. Recently, I stumbled onto an article about research using a modified cell-phone to enable doctors to perform in-situ analysis by turning the phone into a microscope or spectrometer.

The Rock of Saint Michael

One of my fellow graduate students here at Cornell, Kassandra Martin-Wells, is also writer, but unlike me she actually finishes her stories, and they’re very good. She studies cratering on the moon and wrote the following story after hearing a presentation about the moon’s south pole at a Division for Planetary Sciences (DPS) meeting.
